Musannaf Ibn Abi Shaybah 34158 — Reports on the virtue of Umar bin

Mus'ab bin Sa'd (may Allah have mercy on him) reports that Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) said: Surely Umar (may Allah be pleased with him) is in Paradise, and all that the Messenger of Allah (peace and blessings be upon him) saw in sleep and in wakefulness is true. The Messenger of Allah (peace and blessings be upon him) said: "I was in Paradise when I saw a house in it, so I asked: 'For whom is this?' It was said: 'For Umar bin al-Khattab.'"
